Setting Up and Using Your Computer 19
If a drive failure occurs, subsequent read and write operations are directed to the surviving drive. A
replacement drive can then be rebuilt using the data from the surviving drive. Also, because data is
duplicated on both drives, two 120-GB RAID level 1 drives collectively have a maximum of 120-GB
on which to store data.
Configuring Your Computer for RAID
At some point you may want to configure your computer for RAID if you did not select a RAID
configuration when you purchased your computer. You must have at least two hard drives installed
in your computer to set up a RAID configuration. For instructions on how to install a hard drive,
see page 85.
You can use one of two methods to configure RAID hard drive volumes. One method uses the
Intel(R) Option ROM utility, and is performed
before
you install the operating system onto the
hard drive. The second method uses the Intel Application Accelerator, or Intel Storage Utility, and
this method is performed
after
you have installed the operating system and the Intel Storage
Utility. Both methods require that you set your computer to RAID-enabled mode before starting
any of the RAID configuration procedures in this document.
